Abstract
Disclosed is an image forming system having a first mode in which an image forming unit forms toner images and adhesive layers on sheets, and a booklet creation apparatus creates a booklet using the sheets; and a second mode in which the image forming unit forms only adhesive layers on sheets, and the booklet creation apparatus creates a booklet using the sheets. A predetermined temperature of a fixing unit that is set for heating and pressing of a sheet in the fixing unit is lower in the second mode than in the first mode.
Claims10
An image forming system, comprising:
- an image forming apparatus including:
- an image forming unit configured to form at least one of a toner image and an adhesive layer on a sheet, and
- a fixing unit configured to fix the toner image and the adhesive layer to the sheet at a predetermined temperature by heating and pressing while pinching and conveying the sheet;
- and
- a booklet creation apparatus configured to create, in a state in which a plurality of sheets to which adhesive layers are fixed are overlaid, a booklet,
- wherein the booklet is created by heating and pressing the adhesive layers fixed to the plurality of sheets, to bond the plurality of sheets,
- wherein:
- in a first mode in which the image forming unit forms toner images and adhesive layers on sheets, the booklet creation apparatus creates a booklet using the sheets;
- and
- in a second mode in which the image forming unit only forms adhesive layers on sheets, the booklet creation apparatus creates a booklet using the sheets, and
- wherein the predetermined temperature is lower in the second mode than in the first mode, and
- in a case where a number of pages of a booklet created consecutively in the second mode exceeds a predetermined number of sheets, for each subsequent sheet exceeding the predetermined number of sheets, at least one of the predetermined temperature or a conveyance interval of sheets in the second mode is greater than the at least one of the predetermined temperature or the conveyance interval set before the predetermined number of sheets was exceeded in the second mode.
